In my view, since O 12 r 7(1) of the ROC applies to a situation where there is a dispute as to the existence (and not the exercise) of the court’s jurisdiction (see [25] above), one has to consider whether the filing of an admiralty in rem writ without leave of court, assuming such leave is required by statute, would mean that the court’s jurisdiction over the matter would not even exist, or if it means that, in such a scenario, the existence of the court’s jurisdiction is not denied by the commencement of the proceedings without leave, but instead the question is whether it would be appropriate for the court to exercise its jurisdiction to hear the matter. In the former case, the writ may be set aside, while in the latter case, the appropriate remedy might be a stay of the proceedings or a striking out. When I asked counsel for OTPL about this distinction, he did not cite any other authorities, apart from The Hull 308, to support his submission that the Writs may be set aside under O 12 r 7(1). However, from my reading of the judgment in The Hull 308, it is not apparent that this issue was actually raised and disputed by the parties in that case. Also, there is no mention in that judgment as to whether counsel in that case had relied on O 12 r 7(1) as a basis for setting aside.
